The aim of this study was to evaluate the effects of low level laser on the postoperative pain of patients who had to undergo third molar surgery.
In a randomized clinical setting, 100 patients were assigned to two groups of 50 in each. Every patient underwent surgical removal of one mandibular third molar (with osteotomy). After suturing the flap, the soft laser was applied to every patient. In group I laser radiation was applied by the dental assistant with output power of 100 mW, in continuous mode with sweeping motion, in group II, the laser hand piece was only brought into position without releasing energy, so that no patient knew which group he belonged to. The patient was given a pain evaluation form where they could determine their individual pain level and duration.
The statistical tests showed significant difference in pain level between laser and control group (P<0.001) but no significant difference found in pain duration in two groups (P=0.019).
The result of this study verifies the positive effect of the soft-laser therapy in the postoperative complication after third molar extraction.
本研究旨在评估低强度激光对必须接受第三磨牙手术患者术后疼痛的影响。
在随机临床环境中，100名患者被分为两组，每组50人。每位患者均接受一颗下颌第三磨牙的手术拔除（行截骨术）。在缝合皮瓣后，对每位患者应用软激光。在第一组中，由牙科助理以100 mW的输出功率、连续模式并做扫动动作施加激光辐射；在第二组中，仅将激光手持件置于相应位置而不释放能量，以使患者不知道自己属于哪一组。给患者一份疼痛评估表，他们可以据此确定自己的个体疼痛程度和持续时间。
统计检验显示激光组与对照组在疼痛程度上有显著差异（P<0.001），但两组在疼痛持续时间上无显著差异（P=0.019）。
本研究结果证实了软激光疗法对第三磨牙拔除术后并发症的积极作用。
